By exsupported by a folding brace 12, conprolled tending the arms, which carry the end-gate, by a locking-lever 13 and pivotally secured-at over the axle it will be instantly raised a sufits opposite ends to a block 14 and a rod 15.

Rod 15 is secured improvements is that after the pan has been at its opposite ends to cars 17 and the rear locked in an upright position, ready for travwall of the pan and is curved to form a hantoo eling on the road, the end-gate, instead of dedle 18, by which the rear end of the pan may pending from the bail and hanging down in be elevated.

When traveling on he road or back from the dump, the pan is loosely held in an upright position byan elongated hook l9,which automatically engages rod 15 when the pan is raised up. Said hook is pivoted to pin 20, and its movement is limited by its end 21 contacting with lugs 22 on the axle. Its under side is curved, as shown, to permit the upper end of the pan to swing forwardly and its lower end to swing back and over any ordinary-sized obstacle which it may strike on the road. It is to allow this movement of the pan that the axle is held in a slightlyinclined position. In addition toproviding for this movement the other important feature of the invention resides in the manner in which the end-gate employed for closing thefront of the pan is supported and operated. Said end-gate consists of a transverse wall 23, provided with triangular end portions 24, bent at right angles thereto and adapted to close against the vertical front portion of the pan when the scraper is loaded,

and thus hold the dirt therein until dumped.

The end-gate is carried by two arms 25, riveted at their forward terminals to the upper part of the triangular end portions 24 and extend backwardly over the axle and then curve downwardly to pins 26, on which they are pivotally secured.

hen the pan is in an upright position, as shown by Fig. 4, the end-gate is held up by a chain 27, secured at its opposite ends to the upper central portion of the pan, and a hook 28, pivotally secured to the upper portion of the folding brace.

By extending arms 25 over the axle the endgate is immediately raised a considerable dist-ance above the front of the pan when the latter is lowered for loading or (lumping, and consequently does not retard said operation by hanging down in the way of the soil. When the pan is in an upright position, the end-gate is held a sufficient distance ,above the ground by chain 27 to clear any obstacle over which the platform will pass.

Having thus described the invention, what I claim as new, and desire to secure by Letters Patent, is

1. In a wheeled scraper, an axle, a suitable pan, an end-gate for closing one end of the latter, and a pair of arms extending over the axle and rigidly secured at their forward terminals to the end-gate, and pivotally secured at their rear ends to the pan, substantially as described.

2. In a wheeled scraper, an axle, a pan, an end-gate adapted to close one end of the pan, and aims, extending over the axle which are pivoted at their rear ends to the pan, and carry the end-gate at their opposite terminals, substantially as described.

3. In a wheeled scraperprovided with a pan, an axle, a folding brace, and an end-gate; a chain secured at its opposite ends to the folding brace and the end-gate, and adapted to retain the latter in an elevated position by being thrown into engagement with the axle by the folding brace, when the pan is dumped, substantially as described.

4. In a wheeled scraper provided with a pan, an end-gate for closing one end of said pan, and a chain secured at its opposite ends to a suitable part of the machine and the endgate, in such a manner as to retain the latterin an elevated position when the pan is dumped, substantially as described.

5. In a wheeled scraper, a pan, an axle, an end-gate comprising a transverse Wall having triangular end portions bent at right angles thereto, a pair of arms, extending over the axle and secured at their opposite ends onto the side of the pan and the end-gate in such a manner as to elevate the latter above the front of the pan when the latter is depressed, substantially as described.

6. In a wheeled scraper provided'with a pan adapted to be operated by a hand-leve r, the combination of an end-gate, comprising a transverse wall with triangular end portions bent at right angles thereto and adapted to close against the vertical front portion of the pan, a pair of arms rigidly secured at their forward ends to the upper portions of the triangular walls, and which extend back over the axle and then curve downwardly, pins projecting inwardly from the side walls of the pan to which the rear ends of the arms are pivotally connected, and a chain for holding the end-gate in an elevated position when the pan is upright, which is secured at its opposite ends to the end-gate and the folding brace of the scraper, substantially as described.

7. In a wheeled scraper, a pan, a rod secured to the rear wall thereof, a forwardlyinclined arched axle, a block rigidly secured thereto, and an elongated hook pivotally secured at its forward end to the block and adapted to loosely engage the rod when the pan is upright so its lower end may swing backwardly over obstacles in the road, substantially as described.

In testimony whereof I affix my signature in the presence of two witnesses.
